摘要
为了克服现有双丝型检测器无法进行水平、垂直两个方向同时测量同步光位置的缺点,合肥光源新研制了基于四象限光位置检测器的同步光位置测量系统,并使用对数比处理技术进行后续的数据处理。通过分别对光学成像系统和四象限光位置检测器的标定,最终得到基于四象限光位置检测器的光位置测量系统的性能参数为:水平方向灵敏度0.471 2 mm-1,线性范围为±1.83 mm,垂直方向灵敏度0.635 0 mm-1,线性范围±1.32 mm。与合肥光源现有的光位置测量系统相比,具有较高的性价比。
In order to overcome the limitation that the two-wire monitor cannot measure the beam position in vertical and horizontal directions at the same time, a new photon beam position measurement system based on four-quadrant detector has been developed at the Hefei Light Source(HLS), and the logarithmic ratio method is used for data processing. After the calibration of the optical imaging system and the four-quadrant detector, main parameters of the photon beam position measurement system were obtained. In horizontal direction, the linear range is ±1.83 mm, and the sensitivity is 0.4712 mm-1. In vertical direction, the linear range is ±1.32 mm, and the sensitivity is 0.6350 mm-1. The system has a good performance price ratio.
